The Forster Quick Change Jaw Assembly LS-Large is a replacement assembly sized for LS-Large shell-holder jaws and intended for use with compatible Forster Co-Ax presses. It holds cases by the base of the cannelure using spring-loaded, self-acting jaws that open and close as the press handle is cycled. This assembly includes the components required to swap a single side of the S or LS Shell Holder Jaws without disassembling the full jaw unit.
